Text Box: What is Chipless RFID?
A chipless RFID is a fully printable passive microwave/mm-wave circuit that responds to an interrogating signal with a pre-defined frequency, time and hybrid-domain signatures. Since the tag has no application specific integrated circuit (ASIC), the cost of the tag is comparable to the optical barcode.
Text Box: What is uniqueness about Chipless RFID?
A chipless RFID has the potential to remove and/or co-exists with the optical barcode. The tag can also offer flexibility in operation as a chipped tag does. It can also be directly printed on paper and plastic. It is called a smart label.
Text Box: What type of reader is needed for Chipless RFID?
A dedicated reader is designed to read a specific chipless tag. Since the tag is fully dumb without an intelligence chipset, the reader contains all signal processing and intelligence capabilities. Based on the tag types, specific readers are designed. Specific anit-collision and hand-shaking algorithm are designed for chipless RFID system. 
Text Box: What type of Chipless tag MMARS has developed?
MMARS has pioneered in developing frequency signature based chipless tag in both microwave and mm-wave frequency bands. Gen1 tag is a dual-polarised stopband multi-resonator filter also called a re-transmission tag. A mm-wave back-scattering chipless tag is also developed with 29-bit data capacity. A time-domain tag is also designed based on TDR principle. MMARS filed 10 patent applications on inventions and published  12 books, 36 book chapters, hundreds of refereed journal and conference papers are published in the field. So far 15 PhD completions have happened in the field.
